How are polymer fasteners used in medical technology?
Polymer fasteners are widely used in medical technology due to their biocompatibility, strength, and resistance to sterilisation processes. They are often employed in medical devices such as surgical instruments, implantable devices, and diagnostic equipment, where metal fasteners may not be suitable due to the risk of corrosion or adverse biological reactions. Polymers like PEEK and medical-grade nylons are commonly used for fasteners in these applications because they do not react with bodily fluids and tissues, ensuring patient safety.
In diagnostic and imaging equipment, polymer fasteners provide non-magnetic properties, making them ideal for use in MRI machines and other sensitive equipment where metal interference could affect performance. Additionally, their lightweight nature helps reduce the overall weight of medical devices, improving ease of use and patient comfort. Polymer fasteners are also resistant to repeated sterilisation methods, including autoclaving, gamma radiation, and chemical disinfection, ensuring that they maintain their integrity and performance in hygienic environments. This combination of biocompatibility, durability, and versatility makes polymer fasteners essential in the design and manufacturing of advanced medical technology.
